How to Deactivate a SharePoint feature using PowerShell or STSADM

To Disable a SharePoint Feature, you must first determine the scope of the feature. If the scope is Web-based or is a site collection scope, the URL parameter is required. However, if the scope is farm-based, the URL parameter is not required.

Syntax - PowerShell

Disable-SPFeature [-Identity] <SPFeatureDefinitionPipeBind> [-AssignmentCollection <SPAssignmentCollection>] [-Confirm [<SwitchParameter>]] [-Force <SwitchParameter>] [-Url <String>] [-WhatIf [<SwitchParameter>]]

This example disables the "MyCustom" Web site scoped feature at http://somesite.

Disable-SPFeature -identity "MyCustom" -URL http://somesite

This example disables all features in the subsite at http://somesite/myweb.

$w = Get-SPWeb http://somesite/myweb | ForEach{ $_.URL }

Get-SPFeature -Web $w |%{ Disable-SPFeature -Identity $_ -URL $w}

Syntax - STSADM
